Help reading baptismal certificate

Hola,

Can someone help me decipher the names with (??) on this baptismal
certificate?
https://familysearch.org/pal:/MM9.3.1/TH-1-15087-5072-31?cc=1410092&wc=6828034
(left side, last entry)

Here's what I've figured out so far:
Name: Jose Tiburcio Castañeda
Gender: M
Baptism date: 26 Apr 1832
Church: San Cayetano
Birth date: 14 Apr 1832
Birth place: "Cerritos" Atolinga, Zac
Father's name: Julio Castañeda
Mother's name: Ma. del Refugio Gonzales
Paternal grandparents: Antonio Castañeda & Ma. Eugenia (??) de Haro (??)
Maternal grandparents: Salvador Gonzales & Gertrudis Mayorea Mayorga(??)

Also, what does "teniente" de cura mean?

I see (y me da risa), that baptismal certificates say "hijo legítimo" or
"h.l." Does that mean non-legitimate children (called "natural" right?)
weren't baptized? I cannot find my great-grandmother, but I found (some)
siblings. Maybe she wasn't baptized?

Thanks,
Laura
